All geek questions in one place

What big changes in the version of development of Django will consider these errors?

I had fun developing a web application using the Django development version. After some time, I updated version 1.2 alpha 1 SVN-12271. Now I get error messages about cleaning field fields, such as “u'A325 value is not a valid choice.” This is in the selection field without the possibility of invalid selection. In addition, I see that “this field cannot be empty”, when it can be empty. I don’t think this is some form field for modeling attribute indexing error. The application continues to work properly in Django 1.1.1. So, what serious changes have occurred in Django that will take this into account? backward-incompatible changes to http: //docs.djangoproj ect.com/en/dev/releases/1.2-alpha-1/ , but I don’t see anything.

Here are some great tips: 1) My custom check still works fine; only the default check is checked. 2) Fields affect only selection fields, but some selection fields are not affected. 3) Of the affected selection fields, some of them are standard, and some use the undocumented optgroup function, so this does not seem to be a factor. Any ideas?

I really want to get back to the development version because I need new permissions at the object level (at the row level).
